JOSEPH S. OBRIEN, OF NORTH WILBRAHAM, MASSACHUSETTS.

CHURN AND BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 247,513, dated September 27, 1881,

. Application filed January 28, 1881. (No model.)

To all whom it may concern:

Be it known that I, JosEPH S. OBRIEN, of North Wilbraham, in the county of Hampden and State of Massachusetts, have invented a new and Improved Churn and Butter-Vorker, of which the following is a specification.

The nature of my invention consists in a churn provided with attachments for use in The churn is of the rocking type, and has its upper portion fitted to receive the worker, the churn-cover serving as a table for the butter.

In the accompanying drawings, Figure]. is a side elevation of the churn with the worker attached. Fig. 2 isan end view of the same, certain parts being broken away; and Fig. 3 is a vertical longitudinal section of the churn, showing, also, the worker in a modified form.

Similar letters of reference indicate corresponding parts.

A is the churubody, hung by trunnions a at its mid-length on standards I), that are supported on a suitable base.

c is a crank-wheel, sustained by an arm from one standard, b, and d is a rod from the crankpin of wheel 0, connected near the end of the churn-body, so that by revolution of wheel 0 the churn is rocked in the standards.

The churn-body is fitted with a'fiat top, 6, projecting beyond the rounded ends of the body. The sides g of the churn rise above the top 6, and at the ends the top is fitted with cross-strips f. An open box or tray is thus formed at the top of the churn. The apertured center portion, 0, of top 6 is made removable, to give access to the churn, and at one end of the body is a plug, h, held in by the end of a spring, 2'. The bottom of the churn is fitted with a sliding bolt, 70, that may be moved endwise into an aperture in one standard, so as to retain the top 6 horizontal when the apparatus is used as a butter-worker.

l l are blocks or plates, grooved at one side to pass upon tongues 9, that are formed at the upper edges of the sides g. To these plates arms in m are hung by pivot screws or pins m, and the outer ends of arms mare connected by a cross-bar, n,'whicl1 is to be used as ahandle. A roller, 0, is hung on and between arms m, near their pivoted ends, so that when the top.

arms are held inclined to the top 0, in convenient position for working the butter, the bottom of roller 0 shall be slightly above the ob urn- These parts constitute the butter-working attachment, and to render the apparatus more complete a butter-stamp, p,is suspended by a cross-bar, q, between the arms m.

In operation, the churning being complete, the churn is locked by bolt 70, and the portion 6 of the top being removed, the butter is taken out and placed on the top 0. The buttermilk will run freely back into the churn while the butter is being removed, and after the cover 6' is put in place can return by the aperture. The working attachment is then put in place, and the operator, grasping the handle a, moves the arms back and forth, which is permitted by the blocks 6 sliding freely. The roller 0 is thus pressed upon the butter, and the butter rolled out with more or less pressure, as desired. To stamp the butter after working, it is first rolled out to the required thickness, and then the arms on are moved to bring the stamp down, commencing at one end and working toward the other end. The stamped butter is then removed and the balance rerolled for stamping in the same manner.

In Fig. 3 the worker is shown as fitted with a roller having a corrugated or fluted surface. I do not limit myself in that; neither do I confine myself to the worker applied to the particular churn shown.

The balance-wheel and crank mechanism may be dispensed with and the churn worked by grasping either end, suitable handles being provided on the churn.

Having thus fully described my invention, I

claim as new and desire to secure by Letters.

Patent- A churn having the flat top 0 projecting beyond the body, the sides 9, extending above the top, and the cross-strips f at the ends, in combination with the plates Z, connected by tongue and groove with said slides, and having connected pivoted arms at, carrying rolls 0, as and for the purpose specified.
